Attached (diff) is a possible patch:

        * configure.in: readlink -f is system dependent, replaced with 
        python version

1. One could maybe write it as an one-liner:

  $ ls -l /usr/bin/emacs
  lrwxrwxrwx  1 root root 23 Nov 12  2005 /usr/bin/emacs -> 
/etc/alternatives/emacs
  $ ls -l /etc/alternatives/emacs
  lrwxrwxrwx  1 root root 18 Nov 24  2005 /etc/alternatives/emacs -> 
/usr/bin/emacs21-x
  $ python  -c 'import os.path, sys;  print os.path.realpath(sys.argv.pop(1))' 
/usr/bin/emacs
  /usr/bin/emacs21-x
  $

2. It requires python >= 2.2. One could put the python version check 
   elsewhere.

3. the manual doesn't indicate wheter sys.argv is ro or rw --- so
   sys.argv.pop(1) could fail for others, the alternative is to use
   changeqoute's and sys.argv[1] instead, as in diff2

4. one could put the python code in a seperate file, as in diff3, and 
   put readlink.py in python/ or elsewhere
